How to Start a Gas Weed Eater


Gas weed eaters, also known as string trimmers or weed whackers, are an invaluable tool when it comes to lawn maintenance. Their long shaft allows you to reach small places and areas that are difficult to navigate with a lawn mower. They are lightweight, making them easy to operate no matter your size or strength. The convenience of running on gas allows you to take them anywhere. Starting a gas weed eater is easy if you follow some simple steps.

Step 1

Check the weed eater's gas reservoir and, if necessary, add gas. It is best to use a high-quality gas with a high octane level.

Step 2

Put on eye protection. Slide the on-off switch to the "on" position. This switch is located on the shaft, three or four inches below the engine.

Step 3

Locate the primer bulb, which will be on the side of the engine. Depress the bulb three to five times, observing the fuel's progression out of the tank and into the fuel line. When the fuel line is completely full, stop pumping the primer bulb.

Step 4

Locate the choke lever, which is usually just above the primer bulb. Slide the choke to the "on" position.

Step 5

Depress the throttle trigger, which is located on the shaft near the on-off switch.

Step 6

Using a rapid motion, tug the starter cord, then allow it to rewind. Tug it again, still keeping the throttle depressed. If the engine is cold, tug the starter cord a third time.

Step 7

Slide the choke lever to the "off" position. With the throttle still depressed, again pull the starter cord.

Step 8

Rev up the engine several times until it runs smoothly when the throttle is released.
